This combination of a grey plaid wool blazer and charcoal dress pants embodies polish and class. We're loving how complete this outfit looks when completed with dark brown suede loafers. During the winter season, when warmth is above all, it can be easy to surrender to a less-than-stylish ensemble. However, this ensemble is a stark illustration that you can actually stay warm and remain stylish at the same time during the winter season. As a 30-something man, you probably want to start dressing in a sleeker manner. In this case, combos like this prove useful as a source of inspiration.
